Verbena plant named ‘Balcadurp’

ABSTRACT

A new and distinct cultivar of  Verbena  plant named ‘Balcadurp’, characterized by its deep reddish-purple colored flowers, medium green-colored foliage, and moderately vigorous, compact-upright growth habit, is disclosed.

Latin name of genus and species of plant claimed: Verbena hybrid.

Variety denomination: ‘Balcadurp’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbena plant botanically known as Verbena hybrid and hereinafter referred to by the cultivar name ‘Balcadurp’.

The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during May 2014. The objective of the breeding program was the development of Verbena cultivars that have a compact-upright growth habit.

The new Verbena cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Verbena hybrid breeding selection coded 9912-1, not patented, characterized by its medium pink-colored flowers, medium green-colored foliage, and vigorous, spreading growth habit. The male (pollen) parent of the new cultivar is the proprietary Verbena hybrid breeding selection coded 9943-1, not patented, characterized by its medium purple-colored flowers, medium green-colored foliage, and moderately vigorous, compact-upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during April 2015 in a controlled environment in Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since April 2015 in Arroyo Grande, Calif., and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balcadurp’ as a new and distinct cultivar of Verbena plant:

-   -   1. Deep reddish-purple colored flowers;     -   2. Medium green-colored foliage; and     -   3. Moderately vigorous, compact-upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a different flower color, less growth vigor and a different growth habit. Plants of the new cultivar differ from plants of the male parent primarily in having a different flower color.

Of the many commercially available Verbena cultivars, the most similar in comparison to the new cultivar is LANAI Upright Blue with Eye ‘VEAZ0007’, U.S. Plant Pat. No. 23,595. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘VEAZ0007’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have a flower color that is darker         than plants of ‘VEAZ0007’;     -   2. Plants of the new cultivar do not have a different coloration         from the main petal color that forms a true flower “eye” unlike         plants of ‘VEAZ0007’; and     -   3. Plants of the new cultivar are shorter than plants of         ‘VEAZ0007’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balcadurp’. The plants were grown in 4-inch pots for 13 weeks in a greenhouse in West Chicago, Ill. Plants were given one pinch one week after transplant.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balcadurp’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in January 2018 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in West Chicago, Ill. in 4-inch pots for 13 weeks utilizing a soilless growth medium. Plants were given one pinch one week after transplant. Greenhouse temperatures were maintained at approximately 68° F. to 72° F. (20° C. to 22° C.) during the day and approximately 64° F. to 66° F. (18° C. to 19° C.) during the night. Supplemental lighting was used. Measurements and numerical values represent averages of typical plants.
